The S-TEC System 20 Auto Pilot is a single axis Auto Pilot that can reduce the pilot workload in the cockpit by offering roll stabilization, heading input (with qualified heading input), and Nav Trac from an accepted Nav or GPS system. The System 20 is a great option for aircraft that have limited panel space to work with.MORE INFORMATION

System 40 Auto Pilot

The S-TEC System 40 Auto Pilot is a single axis Auto Pilot that can reduce the pilot workload in the cockpit by offering roll stabilization, heading input (with qualified heading input), and Nav Trac from an accepted Nav or GPS system. The System 40 offers the same great features as the System 20 by offering a stand-alone Turn Coordinator and separate 3 ATI Auto Pilot Controller.MORE INFORMATION

The S-TEC System 60-1 Auto Pilot is a single axis Auto Pilot that can reduce the pilot workload in the cockpit by offering heading mode, (with qualified heading input), VOR/LOC intercepts and tracking, LOC back course intercept and tracking, flag warning, course deviation warning, and three level automatic radio coupler gain scheduling. The System 60-1 offers a stand-alone Turn Coordinator and separate 3 ATI Auto Pilot Controller.MORE INFORMATION

Two Axis Auto Pilots (Roll and Pitch Axis)

System 30 Auto Pilot

The S-TEC System 30 Auto Pilot is a two axis Auto Pilot (Roll and Pitch) that can reduce the pilot workload in the cockpit by offering roll stabilization, heading input (with qualified heading input), Nav Trac from an accepted Nav or GPS system, Pitch Trim Annunciation, and Altitude Hold. The System 30 is a great option for aircraft that have limited panel space to work with, but want the most value for their investment.

System 55X Auto Pilot

The S-TEC System 55X Auto Pilot is a Full Function, two axis Auto Pilot that can reduce the pilot workload in the cockpit by offering heading mode, VOR/LOC intercepts and tracking, LOC back course intercept and tracking, flag warning, course deviation warning, vertical speed control, altitude hold, and Glideslope coupling.
MORE INFORMATION

As opposed to “tracking”, which
essentially is reacting to signal input, GPSS anticipates course changes. When approaching a waypoint, for example, GPSS transitions to a new leg by anticipating arrival at the waypoint, and initiating a coordinated turn so that the
aircraft is established on the new heading without overshooting or under-shooting the new course.
MORE INFORMATION

The 30 ALT can be installed as
stand-alone pitch axis autopilot, and can complement any brand of existing roll axis autopilot. The system 30 ALT is
not dependent on aircraft altimeter or attitude gyro. Iinputs are derived from the systems’ solid state absolute pressure transducer and an accelerometer.

System 60 PSS

The 60 PSS can be installed as
stand-alone pitch axis autopilot, and can complement any brand of existing roll axis autopilot. The 60 PSS can operate as an altitude hold, vertical speed and glideslope coupling system. The system 60 PSS is not dependent on aircraft altimeter or attitude gyro. Inputs are derived from the systems’ solid state absolute pressure transducer and an accelerometer.
